STOVE-BOARD.

SPECIFICATION forming part of Letters Patent No. 247,389, dated September 20, 1881.

- Application filed August25,1881. (No model.)

To all whom it may concern Be it known that I, HENRY G. IVIILLIGAN, a citizen of the United States, residing at South Orange, New Jersey, have invented new and useful Improvements in Stove-Boards, of which the following is a specification.

Prior-to my invention the disadvantages of heating and other stoves resting directly upon the floor was felt, and a means was sought for protecting the same from the radiated heat and falling coal and ashes. This resulted in the production of what has become well known in the trade as sheet-metal stove-boards. Various improvements have from time to time been suggested, involving peculiarities of construction, and having in view the strengthening and beautifying of such boards; and with special reference ,to the beautification of the same it has been suggested to ornament them byembossing a design thereon-that is, raising a given design around the board near its circumference, or at any other desirable locality. In this class of boards so ornamented it has been found that while .the ornamentation serves to beautify the board it also forms receptacles between the embossed surfaces or salient points for the reception of coal, ashes, dirt, &c., and that the removal of the same is quite troublesome and difficult.

The object of my invention is to overcome in a great measure this last-named disadvantage, and at the same time to produce a highlyornamented board, the character of the ornamentation to be such that while it will avoid the accumulation of dirt in a great measure, it is also protected from undue wear and obliteration; and with these ends in view my invention consists of a sheet-metal stove-board having near its circumference, or at any desired location, a pleasing design impressed or indented in the surface of the metal, such impressed or indented design being-partially filled with a contrasting cement or paint to bring out in relief the metal between such design, and give to such portions of the metal the appea-rance'of embossed surfaces, such apparently-embossed surfaces serving as a protection against the defacement or abrasion of the cementor paint, as will be hereinafter more fully explained.

In order that those skilled in the art to which my invention appertains may fully understand the same, I will proceed to describe the peculiarities of construction, referring by letters to the accompanying drawings, in Which- Figure 1 is a plan view of a portion of a stove-board embodying myinventiomand Fig. 2 a section taken at the line 00 00 of Fig. 1.

Similar letters indicate like parts in both figures.

A represents an ordinary sheet-metal stoveboard, stiffened and strengthened by continuous embossed beads B B, concentric with the center point of the board, the outer edge of the board being formed with a stiffening-bead, as shown, and in addition thereto it may be strengthened by radially corrugating the same and bending it under, as fully described in Letters Patent to John S. Brooks, dated January 23, 1877.

0 represents a design, of any desired character, impressed in the top surface of the board by revolving rollers or dies, leaving the metal D between and surrounding said design in about its original plane.

E is a coating of cement or paint, of any suitable and contrasting color, placed upon the impressed or indented design. This cement or paint E, when dry, is designed to have its upper exposed surface slightly below the plane of the surrounding bright metal, so that while it affords little if any opportunityfor the accumulation of dust and dirt, it is safely guarded by the surrounding metal from abrasion or de facement.

It will be observed that the relation of the salient parts of the metal and the guarded and contrasting paint or cement is such that the contrast is always preserved, and is enhanced by any and all wear or cleansing of the salient parts of the metal.

There are many ways which may be adopted for producing my improved stove-boards, the most desirable method so far suggested, but which I do not claim as of my invention, bein g to rollin the design between revolving dies or rollers, then to paint over or cover the indented and salient designs formed by such rolling-in process with paint or semi-fluid cement, and subsequently, when said colored paint or cement has partially or sufficiently dried or hardened, to turn the stove-board upon a flat surface and upon a pivot passing through its center, and to skim or scrape off the paint or cement from the salient parts of the metal by a chisel or other suitable. instrument, leaving the intaglio portions perfectly covered.

It will be observed that the points of juncture between the impressed or indented and salient portions of the metal are not abrupt angles, but are, by the nature of the rolling-in process and the character of the metal, (such as is ordinarily used for the purpose,) slightly arched or curved, so that the colored paint or cement creeps up and clings to said surfaces, and even after the salient parts of the metal shall have become slightly worn there will still remain an intaglio design.

I do not wish to secure by Letters Patent an improvement in the art of ornament-mg metal; but

What I do claim is- As a new article of manufacture, a sheetmetal stove-board having ornamental figures impressed or indented therein, such ornamental figures being covered in the manner described with a paint or cement, to produce contrast and prevent accumulation of dirt, While said paint or cement is protected from wear, substantially as hereiubefore set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

HENRY O. MILLIGAN.
